# It's really simple:  Just load from one charset, save using another.

$sb = New-Object Chilkat.StringBuilder

# In this case, my test file has some norwegian chars in the utf-8 encoding
$success = $sb.LoadFile("qa_data/txt/norwegian_chars.txt","utf-8")

# We could just as well write over the file we just read in.
# (But I don't want to do that for my example..)
$success = $sb.WriteFile("qa_output/norwegian_chars.txt","windows-1252",$false)

# Note:  Windows-1252 is a 1-byte per char encoding, which means it's only capable of representing
# those chars in Western European languages.   See https://en.wikipedia.org/wiki/Windows-1252
# 
# utf-8 is an encoding that can handle chars in any language, including Chinese, Korean, Japanese, Arabic, Hebrew, Greek, etc.
# If a text file contains chars in these other languages, obviously it cannot be converted to windows-1252 because
# there are only 256 chars that can possibly be represented in a 1-byte per char encoding.
